  1. Biodiversity
    the variety of different types of life found on earth
  2. Protect
    to legally guard from harming  a species that is listed as endangered, threatened, or of special concern.

    e.g. elephants, Black Rhino
  3. Biodiversity hotspot
    a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction
  4. Community
    is the study of the interactions between species in communities and interactions between coexisting populations.

    a coral reef, the fish, coral,  and algae are included in this ecosystem.
  5. Dominant Species
    the degree to which a taxon is more numerous than its competitors in an ecological community

    The kangaroo is a dominant species on the Australian savanna.
  6. Keystone species
    a plant or animal that plays a unique and crucial role in the way an ecosystem functions

    A sea otter controls the sea unicorn population
  7. Captive breeding
    the process of breeding animals outside of their natural environment in restricted conditions in farms, zoos or other closed facilities

    e.g. the giant panda
  8. Ecosystem engineer
    an organism that modifies, creates or destroys habitat and directly or indirectly modulates the availability of resources to other species 

    e.g.Beavers
  9. Succession
    the observed process of change in the species structure of an ecological community over time
  10. Habitat loss
    the process in which natural habitat is rendered functionally unable to support the species present

    e.g. we use the  forest  for logging we cut down trees which are habitats to birds
  11. Deforestation
    the permanent destruction of forests in order to make the land available for other uses
  12. Alien species
    plants, animals other organisms that are non-native to an ecosystem, and which may cause economic or environmental harm

    e.g. Harmonia axyridis (Harlequin ladybird)
  13. Invasive species
    a plant or animal that is not native to a specific location (an introduced species)

    e.g. The Black Rat, The Asian Tiger Mosquito
  14. Overexploitation
    harvesting species from the wild at rates faster than natural populations can recover

    e.g. we overexploited cod fish
  15. Extinction
    the end of an organism or of a group of organisms (taxon), normally a species.

    e.g. dinosaurs, dodo bird
  16. Biodiversity crisis
    Biodiversity crisis is declining rapidly throughout the world.
  17. Restoration ecology
    he practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action.
  18. Reforestation
    the natural or intentional restocking of existing forests and woodlands that have been depleted, usually through deforestation.
  19. Biocontrol
    the control of a pest by the introduction of a natural enemy or predator.

    bringing in the golden toad to control the population of monitor lizards
  20. Bioremediation
    using plants and bacteria to absorb the toxins.

    e.g. old gas stations use plans to absorb the toxins so the area can be used again
  21. bioaugmentation
    The process of using plants to add nutrients to depleted soil
